My present invention has reference toV a Afendsidispo:seid.in a line'with the pipe (irornheating device .for automobiles or similar..-l the' exhaust manifold formed with a central lrnotor propelled vehicles.

The inner. end ofthe flue l water jacket or drum arranged in an auxil-.4 isfc'lo'sed, as at- 8, and this ,end'terminates iary muffler connected with the exhaust pipe"4 alfsuitable distance away from theV closed of the engine, and directed there roml/oiter endvof the boiler.

This pipe has an tween the exhaust pipeV and the niuiier 4. oiiset branch 12 provided at its outer end A similar but oppositely directed branch lwith an upwardly directed funnel extension pipe is also attached to the outlet end ot` 13,11 closurev 14 being provided for the funthe exhaust pipe, and the branch pipe 6 comnel.

The boiler connected to'radiators 1S and 19 respective 8 comprises a tubular member of a length ly. The outletendsot' the radiators have less'than that of the ninther T. rThe water connected therewith short pipes 20 and 2l aclet is closed at both of its ends, but has its respectively forming branches ot the main pipe 22 that is directed into the hollow een#v ter of the boilen It is, kof course, to
